Whatever looks good sounds interesting... maybe right in the middle of the hood, that way the passenger can see it also

I think Vikki has a template on her site showing dimensions off the corner of the hood. I used one but I think it was for a 68 and realized before I started cutting too much. Used a hole saw to get the hump that sticks down centered in the traingual spot under the hood. Then needed to square out one end of the hole with a tin snips. Make sure to use a sharp new hole saw.

Hey Gus, is your hood factory with the tach? Got all your measurements. Tried to go to vicki's website waited about 10 minutes for it to download template. My dial-up sucks long story. I finally gave up due to Aadd syndrome.

Thx david, now the fun part.... CUTTING. I'm thinking of using my concrete saw? You know keep the holes from getting all burred up. Was going to us the hedge trimmers but don't think they are sharp enough...

I used a 4" metal hole saw for mine (after-market tach on a '69). Worked just fine. Just make sure it is sharp, a dull one will heat up the hood without cutting into it. This can cause the paint to blister. Good luck!

Well it's on the car... Man is the 67 tach a tall tach!!! Not sure about it. Figured for the purists I'd gotten harassed about the wrong tach if I went with the 68 tach. I think it will grow on me. My mother loves it per her words "paint it red with black vinyl top I'll be happy". She had a 68 bird with hood tach.

Funny this would be mentioned about the 67-68 tachs. My 68 Bird had an original 68 short style tach. Then when I bought the one to put on the LeMans, I ordered the correct 67 tall style. At first, I could NOT get used to it at all. I almost ordered a 68 style. However, after a few months have past, I have completely reversed myself and now I like the 67 taller tach much better!

A true Pontiac signature. I can't imagine owning a Pontiac without the infamous hood tach. That's why I just had to put one of the 67 LeMans, I clarified that it was an available option before cutting into a flawless hood!

Drove the car today since putting the tach out there and have to say it looks mean out there. It seems to be fairly accurate too. Can't wait to see it glowing at night cruising the cool autumn air. Now I need to find me a ram air pan and open those scoops up.. No lowe's or homedepot air duct system... But true ram air power!!!
